BUTTONrFEEDING MECHANISM FOR BUTTON-SETTING MACHINES.

' To all whom it may concern: I

Be it known that I. FREDERICK'E. gran- LEY. a citizen of the United States, res1dmg at \Vaterbury, in the county of N ew Haven and State of Connecticut, have invented a certain new and useful Improvement in Button-Feeding Mechanism for Button-Setting 'Machines. of which the following is a full,

clear, and exact description.

This invention relates to the type of button-setting machine illustrated in the case of Stanley and Leggett, filed May'lO, 1915, Serial No. 27,042, and has'special reference to the button-turning feature by which the buttons as they come one by one from the hopper or turret through the raceway or chute in an edgewise position. are given a quarter turn so as to present them horizontally-to the means by which they are placed in operative relation to the tack or other fasarticle.

The lnvention hereln conslsts of a reciprocating cut-off or escapement which drops the button edgewise upon the inwardly inclined bottom of a pocket, when by gravity it topples over upon an inclined wing on the ejector, and thereupon upon the retreat of the ejector the button by gravity completes a quarter turnover into'the raceway of the ejector and lies horizontally therein, whence it is removed by theforward movement of the ejector and delivered to the means by which it is ultimately placed in position to be set, as I will proceed to explain and finally claim. I

In the accompanying drawingsillustrating the invention, in the several 'figuresof which likeparts are similarly designated, Figure 1 is a side elevation of suliicient of a button setting machine to illustrate the operation of the present invention. Fig. 2 is a front elevation of the parts shown in Fig. 1. Fig. 3 is a perspective view of the button turner. Fig. an; a horizontal section of the button turner takenjust above the ejector.

into a position it would occupy to receive a button in its fallifrom the cut-off and showlng the button in dotted lines.

1 may represent the head of the machine,

on which is mounted a main shaft 2, and which may carry a button turret from which extends the button chute 3 anda tack or rivet turret from which extends the tack chute 4 as in the case above referred to. At

vthe end ofthe button chute is an auxiliary chute 5, having a transverse raceway 6 in which s arranged the cut-off or escapement 7, having an outwardly projecting pin 8 which is connected by a link 9 with arocklever 10 pivotally mounted at 1]. onsome part of the head and terminating in acam-. roller 12 which is actuated by a cam 13 on the main shaft 2 and a spring 13* in such way as to reciprocatethe cut-off or escape.

ment tomove its slot 14 first into alinement with the chute slot 15 and then into alinement with the pocket 16 formed in they auxiliary chute 5. The bottom of this pocket is provided with abeveled portion 17.. Next to the bottom of the pocket .is abase-plate 18 having a raceway 19 in which is a reciproeating slide 20, preferably provided with an outwardly inclined wing 21. This slide20,

herein designated the ejector, is providedv with a screw threaded extension 22 on which is adjustably secured a; grooved collar 23 which 1s engagedby a-tracker 24: swiveled in a lever 25 which is plvoted at 26 in co nnection with the head and at its other endis v provided with a cam-roller 27 which is acted upon by a cam 28 on the main shaft 2 and a spring 28 to vibrate said lever and thereby impart a longitudinally reciprocating 'motion to the ejector.

The leading end of the ejector may be i provided with a finger 29.

The discharge end of the auxiliary chute may be cut away orgrooved at 30 and 31 to receive abutton.

As indicated in Fig. 3, the button 32 de scends the chute on edge andfalls into'the escapement 7 in this position and then when the escapement is moved to the right, Fig.3, thebutton drops from the escapem'ent into the pocket 16 and its edge striking upon the beveled portion 17 the button gravitates outwardly. In the operation of the machine the ejector at this time stands with its wing 21 opposite the buttonand the button topples over. hub down, against the wing, as indicated by the dotted lines in Fig. 5, and then the ejector is moved to the left so as to remove its wing from its button supporting position, whereupon the button fall s, hub down, into the-recess or groove of the auxiliary chute in advance of the ejector, and

thereafter the ejector is moved to the right and pushes out the button into the means by which it is carried and held in position to receive the tack or rivet or other attaching or fastening medium. The finger 29 projecting slightly overthe leading end of the ejector extends over the top of the button and insures the proper engagement of the ejector with the button and its discharge.

Any suitable button transferring mechanism for receiving the button from theejector and presenting it to the fastener may be used. such, for example, as that explained in the case hereinabove referred to. The tack feed and its appurtenances also may be as in the case hereinabovereferred to; but for convenience of reference, I have shown herein the button transferring mechanism as comprising a button holder 33, and I have shown the reciprocating. setting anvil 34c and the tack placing and setting mechanism 35, all substantially as in the case referred to, the novel feature of the present invention comprising the turner, as already stated,

The wing 21 may or may not be used, as desired, although it is an eflicient means for insuring the proper positioning of the button for its ejection from the chute to the button holder by which it is presented to the setting mechanism, it being understood that the button in order to be set must be turned from its edgewise position incident to its descent in the button chute to a horizontal position with its face up and hub or shank down. as shown in dotted lines in F ig. 4. It is within my invention also to omit the beveled portion 17. but it is advisable to employ either the beveled portion 17 or the wing 21, in order to insure the toppling over of the button from its edgewise to its horizontal position, and both the beveled portion and the wing may be used. These and other'variations are within the spirit and scope of the claimed invention.v

What I claim is 1. In a button setting machine, a button chute down which the buttons descend edgewise, and-an auxiliary chute at thedischarge end of the button chute provided with a pocket communicating with the button chute, a cut-oif or escapernent interposed between said pocket and thebutton chute to transfer the button from the button chute to the pocket, a beveled element onto which the button falls in its escape from the button chute and which causes the button to gravitate from its edgewise to a horizontal position, and means to eject the button from the auxiliary chute. V r

2. In a button setting machine, a button chute down which the buttons travel edgewise, and an auxiliary chute at the discharge end of the button chute having a button re- 7 ceiving pocket, a cut-off or esoapement interposed between said pocket and the'button chute to transfer the button from the button chute to the pocket, and a beveled element in the bottom of the pocket on which the button is dropped from the cut-off or escapement to assist gravity in turning the button from an edgewise to a horizontalposition'in the bottom of said auxiliary chute,

v and a horizontally reciprocating ejector ar ranged in the bottom of the auxiliary chute and operating in line with the horizontally placed button.
